To be a zombie or not to be a zombie? This is the question asked in Braains.io, an online multiplayer survival game in which you can play the role of a human or a zombie. As a human you will have to do everything to hide and protect yourself from the coming zombies. Find a place that seems secure and move objects around to create protective barricades that will slow down the zombies or prevent them from reaching you. If you get hit you will become a zombie yourself and you will have to infect the other remaining human players. At the end of the time of each round, if there are humans left they will be the winners and on the contrary, if the zombies have succeeded in infecting all humans they will win the game.
